12. How can water move from one tracheid into a neighboring cell?

Biology
1 answer:
olganol [36]2 years ago
5 0

Answer and Explanation:

12. The water has a lower osmotic pressure than the cell sap of the root hairs. Due to the osmotic difference water is drawn by osmosis across the cell wall and cell membrane into root hairs. Water moves by osmosis into adjacent cortex cells and their osmotic pressure is lowered drawing water by osmosis. Water passes to the successive cortex cells and through the endodermis to the xylem vessels. At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the veins and enters the cells of the spongy and palisade layers.

13. Food and other manufactured material are translocated by the phloem. They enter the sieve elements through plasmodesmata connecting them to adjacent companion cells which are sites of high metabolic activity. The manufactured food are translocated through sieve tube along the cytoplasmic strands.

What statement correctly describes the relationship among endocrine glands, target cells, water-soluble hormones, and lipid-solu
9966 [12]

Water-soluble and lipid-soluble hormones that bind to target cells are secreted by endocrine glands.

The interaction between endocrine glands, target cells, water-soluble hormones, and lipid-soluble hormones is accurately described by the aforementioned sentence.

<h3>What functions and how does the endocrine system operate?</h3>

The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking into the cells they intend to reach.

When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormone when levels fall below a certain threshold.

Homeostasis is a process that functions similarly to your home's thermostat. Almost every physiological process is impacted by hormones, including:

  • Metabolism
  • Growth & development.
  • Emotions & mood.
  • Fertility & sexual function.
  • Sleep.
  • Blood pressure.

What is the purpose of the electron transport chain in the thylakoid membrane?
Feliz [49]

Answer:

To produce energy in form of ATP

Explanation:

The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors.  These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP.  Later on these electrons will reach the other photosystem, to produce reducing power.  This is in plants.

Cyclic photosystems also exist, in some bacteria, for example,  and only produce energy as ATP.  They also have an electron transport chain.

1. What molecule carries chemical energy that cells use for their functions?
Assoli18 [71]

Answer:

adenosine triphosphate

Explanation:

Your energy does come from food, but not directly. All cells, like that in Figure 1.1, use chemical energy carried by ATP— adenosine triphosphate. ATP is a molecule that transfers energy from the breakdown of food molecules to cell processes.
